Need help to convert a logo

I am really sorry but not very good with GIMP. I can do basic things, but this is a bit more complicated for me.

So will appreciate if anyone has any spare 5 min to do me a big favour:

Need to convert the attached image to a mono chrome so can be prined on a T shirt:

Need to have the following changes:

1) The back ground will be removed from white to transparent.
2) Ball will be pure white
3) The green colour will become transparent.
4) The letter 'A' will be white
5) The square where the letter A is at the moment need to change from Blue to transparent.
6) EGON will become transparent
7) line under EGON and 'team tennis' will also become transparent.

Any help will be much appreciated.

Is it possible to be converted to a format that will have a good quality for printing on T shirts.
